The Physx based rope object would either be setup with mods or with scripts.
Scripting commands for this object would include: length, width, weight, elasticity, breaking strength, multiple locations on the rope, break the rope, fix the rope, and a few other commands.
Variable length soft links (Like ropes, 2 point linkages for vehicle to vehicle towing, cargo slinging, attaching backpacks to paratroopers)
Variable length hard links (Like tow-bars, same as ropes but a solid connection instead of soft)
